Class CharsetICU

java.lang.Object
  extended by java.nio.charset.Charset
      extended by com.ibm.icu.charset.CharsetICU
All Implemented Interfaces:
Comparable

public abstract class CharsetICU
extends Charset

A subclass of java.nio.Charset for providing implementation of ICU's charset converters. This API is used to convert codepage or character encoded data to and from UTF-16. You can open a converter with Charset.forName(java.lang.String) and forNameICU(java.lang.String). With that converter, you can get its properties, set options, convert your data.

Since many software programs recogize different converter names for different types of converters, there are other functions in this API to iterate over the converter aliases.

Status:
Draft ICU 3.6.

Method Detail

contains

public boolean contains(Charset cs)
Ascertains if a charset is a sub set of this charset Implements the abstract method of super class.

Specified by:
contains in class Charset
Parameters:
cs - charset to test
Returns:
true if the given charset is a subset of this charset
Status:
Stable ICU 3.6.

forNameICU

public static Charset forNameICU(String charsetName)
                          throws IllegalCharsetNameException,
                                 UnsupportedCharsetException
Returns a charset object for the named charset. This method gurantee that ICU charset is returned when available. If the ICU charset provider does not support the specified charset, then try other charset providers including the standard Java charset provider.

Parameters:
charsetName - The name of the requested charset, may be either a canonical name or an alias
Returns:
A charset object for the named charset
Throws:
IllegalCharsetNameException - If the given charset name is illegal
UnsupportedCharsetException - If no support for the named charset is available in this instance of th Java virtual machine
Status:
Draft ICU 3.6.
